The Mixed-Up IAQ and Infiltration Limit Blues

The ventilation wars inspired this song by Eric Werling

Posted on Dec 18 2013 by Allison A. Bailes III, PhD, GBA Advisor

Last week, I caught the second day of Building Science Corporation's Experts' Session. (Click the link to download the presentations from the BSC website.) Joe Lstiburek spoke the whole day about ventilation, and I’ll be writing an article about that soon. At the end of that day, though, we got a little surprise.

Eric Werling got up and gave a short presentation, making some recommendations on reconciling the differences between Joe and the ASHRAE 62.2A standard for residential mechanical ventilation systems established by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers. Among other requirements, the standard requires a home to have a mechanical ventilation system capable of ventilating at a rate of 1 cfm for every 100 square feet of occupiable space plus 7.5 cfm per occupant. committee (more on that later as well, after I get a copy of his presentation). He also performed a great little song about the ventilation wars. Here it is, with the lyrics below.

Enjoy!

Mixed up IAQ and Infiltration Blues

by Eric Werling

Well, ASHRAEAmerican Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE). International organization dedicated to the advancement of heating, ventilation, air conditioning, and refrigeration through research, standards writing, publishing, and continuing education. Membership is open to anyone in the HVAC&R field; the organization has about 50,000 members. standard 62-89 was really fine
Way back in nineteen hundred eighty nine.
Then Max and Joe, they came along,
And ever since I been singing this song:
Got those mixed-up IAQ and infiltration blues.

One thing led to another,
Now houses are really tight.
Test and seal all day long
Till there ain’t a leak in sight.

Just be careful when you’re caulking in it
Not to pass that building tightness limit,
I got those mixed-up IAQ and infiltration blues.

Now Max and Joe started getting rough,
Pretty soon they were slinging stuff
About a lousy 2 cfm per hundred square foot credit.
A hundred times I think I’ve read it,
And I’ll be damned — I still don’t get it,
I got those mixed up IAQ and infiltration blues.

But now I don’t feel so bad,
I don’t feel like I’ve been had,
Because my building science buddies are all confused too.

Just be careful when you’re caulking in it
Not to pass that building tightness limit,
I got those mixed up IAQ and infiltration blues.
I said, I got those mixed-up IAQ and infiltration blues.
Yeah, I got those IAQ mixed-up abba-dab blues.
